from Signal Notes · host Nick Creighton

BUILD LOG 046 why your ai agent keeps hallucinating nick walks us through the night his client's inventory went 847% over reality. twenty minutes from a $2.3 million disaster. it wasn't the model—it was the guardrails. this is production-level thinking. after running thirteen sites with live AI agents, nick learned that even gpt-4 makes stuff up roughly one time out of every five in complex workflows. nobody ships prepared for that. most teams just pray. the fix? three layers of defense that actually catch hallucinations before they hit your database, your customers, your bottom line. layers of output validation, semantic checks, and external truth-testing. unglamorous. unsexy. essential. a meditation on the gap between ai demos and systems that won't cost you six figures. listen in: Build Log on Transistor Related Reading 10 AI Tools for Building Automated Income — WealthFromAI How to Use ChatGPT for Business — WealthFromAI AI Affiliate Marketing Strategy — WealthFromAI 10 Ways to Make Money with AI — WealthFromAI Understanding AI Hallucination Problems and Solutions — AI Discovery Digest
